Specification of Letters fPatent.

Patented Mar. 2, 1920.

To all whom it may concern:

Be it known that I, FRANK O. HOAGLAND, a citizen of the United States,and resident of Bridgeport, in the county of Fairfield `and State ofConnecticut, have invented certain new and useful Improvements in Vises,of

which the following is a specification.

My invention relates to new and useful improvements in vises of theswivel type, adapted to be secured to a bench andadjusted to differentpositions for holding work therein.

The object of the invention is to provide an improved construction ofvise wherein the front jaw is stationary and the rear jaw is made tomove to and from the work and front jaw. To provide a clamping screwwhose opposite end portions are supported in the flXed jaw member, andwhose intermediate portion is in engagement with the movable or rear jawin a way to operate the same, thereby providing three bearings orsupports for the screw in a manner to form a firm engagement of the samewith the coacting parts. Further to construct the vise so that the screwand connected parts contained within the front portion of the vise willbe covered and inclosed, and finally to include a saddle havinglongitudinal ways and between which the movable rear jaw is slidablymounted.

With these and other objects in view, the

Vinvention comprises novel features of construction and combination ofparts shown upon the accompanying two sheets of drawings forming a partof this specification, and upon which similar characters of referencedenote like or corresponding arts throughout the several gures, an ofwhich:

Figure 1 shows a top plan view of my improved form of vise complete.

Fig. 2shows a central vertical longitudinal section of the same taken online --m of Fig. 1. f

Fig. 3 is a front end view, and

Fig. 4 shows a cross section taken on line 1 y of Fig. 1.

,Referring in detail to the characters of reference marked upon thedrawings, 6 indicates a bed which is provided with pockets 7 to receivescrew bolts for securing the vise to a bench. This bed is provided witha circular hub portion 8 that fits into the round pocket 9 in the underside of the saddle l0 which is adjustably rpositioned thereon. A nannular shouldered slot` 11 is formed in the bed to receive the head ofthe bolts 12,` carried in the saddle, and which are provided with nuts13 for securing the sad dle to the hed.

The saddle is of an elongated shape and has a longitudinal way 14 formedin the central portion of its top side' to receive the base 15 of themovable rear jaw 16, and in addition is provided with longitudinalgrooves 17 positioned in the opposite side walls of the pocket 14 toreceive the end of the plates 18 secured to the opposite side portionsof the base of the movable jaw by means of screws 19 whereby the saidjaw is held down against the saddle. The front end portion of the baseof the movable jaw is provided with a bearing 2O in which the threadedbushing 21 is positioned to be engaged by the clamping screw 22.

The front jaw, which I have designated as 23 and which I have alreadyreferred to as being a fixed jaw, is secured to the saddle by means ofscrews 24 and 27 and is further provided with ribs 25 that arepositioned in the cross pockets 26 formed in the two longitudinal topsurfaces of the side portions of the saddle to better hold the fixed jawin position and to relieve the strain from the screws 24 and 27. Thisfixed jaw member together with its extended hood portion 28 thus bridgesthe longitudinal way 14 and the base 15 of the movable jaw 16, as wellas the clamping screw 22 before mentioned. An apron 29 is formedintegral with and disposed downwardly at a right angle from the topsurface of the hood in a way to cover the front end of the way 14 and toprovide a front bearing for the clamping screw 22.

The clamping screw, as will be noted, is provided with three points ofengagement for the purpose of affording a more reliable operation and amore rigid engagement of the screw with both the fixed and movable jawmembers and, as will be further noted, has two bearings in the Xedmember and one in the movable member. In addition to the bearings 30 inthe apron for the forward end of the clamping screw I also provide abearing 31 in the back of the jaw for the inner end 32 of the screw, andI also position a hardened steel bushing 33 between this end of thescrew and the jaw so as to prevent? wear of the jaw member, whereby amore permanent and rigid bearing for the screw is obtained. The bushing2l carried by the base l5 of the movable jaw member thus serves tooperate on the intermediate portion of the screw and between its twobearings as aforesaid and is thus rigidly supported so as to avoid anytendency of the screw to spring or the jaws to glve. y

The construction further serves to provide a direct connection betweenthe fixed jaw and the movable jaw and includes spe- Lacasse what I claimand desire to secure by Letters Patent, is

1. In a vise of the class described, the combination of a base member, ajaw liXed thereto, a hood carried by said base and spaced therefrom, anapron depending from said hood and terminating adjacent the base member,a movable jaw, a slide carrying the movable jaw and mounted on the basemember, an operating screw having a thrust bearing in said xed jaw,journaled in said apron and operatively associated with said jaw slide.

2. The structure called for by claim 1, characterized in that a threadedbushing is carried by the inner end of the slide with the operatingscrew extending therethrough.

Signed at Bridgeport in the county of Fairfield and State of Connecticutthis 27 day of March, A. D. 1919.
